Error building Unit Tests (UT)

[sudha-zetta]

I am trying to build the UnitTest (UT) directory in libest 3.2.0 and it looks like same files are missing.

$ make
gcc -I../../src/est -I../.. -I../util -I/usr/local/ssl/include -I/usr/local/curl/include -I/usr/local/include -I/include -I/include -Wall -g -DHAVE_CUNIT -DNO_SSL_DL -c runtest.c -o runtest.o
runtest.c:16:25: fatal error: CUnit/Basic.h: No such file or directory
#include "CUnit/Basic.h"
^
compilation terminated.
make: *** [runtest.o] Error 1

I looked into the Makefile and removed (-DHAVE_CUNIT) under CCFLAGS, but I get error ( not just warnings).

CCFLAGS = -Wall -g -DNO_SSL_DL $(CURL_CC_DEFINE) $(CFLAGS)

$ make
gcc -I../../src/est -I../.. -I../util -I/usr/local/ssl/include -I/usr/local/curl/include -I/usr/local/include -I/include -I/include -Wall -g -DNO_SSL_DL -c runtest.c -o runtest.o

Any suggestions on how to fix this to run some tests? I am using CentOS 7.6

Thanks,
